▎ 摘　　要

NOVELTY - Polyurea coating comprises a component (I) and a component (II). The component (I) is a semi-prepolymer component prepared by reacting 40-60 pts. wt. isocyanate, 40-60 pts. wt. polyester polyol and 1-10 pts. wt. graphene slurry. The component (II) comprises 10-30 pts. wt. chain extender, 15-30 pts. wt. polyether polyol, 40-60 pts. wt. terminal amino polyether, 1-10 pts. wt. graphene slurry, pigment and trace-additives. USE - Polyurea coating (claimed). ADVANTAGE - The polyurea coating has excellent blast-proof property, impact resistance, physical strength, shear resistance and low-temperature flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing the polyurea coating, which involves spraying the component (I) and the component (II) in a ratio of 1:1 using a high-pressure spraying apparatus to obtain the polyurea coating.
